session: fix allocation of proxy fifos

Fifos need to be synchronously allocated once a transport like tcp
accepts a session. Since events are now delivered asynchronously,
proxy apps must explicitly register a cb function that manages
fifo allocation prior to being notified of connect event.

Type: fix
Fixes: 0242d30
